A nutritionist compared the effectiveness of an online diet program to that of an in-person diet program. After three months, she compared the number of pounds of weight lost. The control group (in-person) lost a mean of 18.00 pounds (s = 14.50, n = 16) and the experimental group (online) lost 16.00 pounds (s = 13.30, n = 21). Use an alpha of .05, a two-tailed test, s2pooled = 191.19, and sM1−M2 = 4.5 to determine if there is a difference between the two programs.

Question

A nutritionist compared the effectiveness of an online diet program to that of an in-person diet program. After three months, she compared the number of pounds of weight lost. The control group (in-person) lost a mean of 18.00 pounds (s = 14.50, n = 16) and the experimental group (online) lost 16.00 pounds (s = 13.30, n = 21). Use an alpha of .05, a two-tailed test, s²_pooled = 191.19, and s_M1−M2 = 4.5 to determine if there is a difference between the two programs.
